We upgrade our LDM machine halo.sci.ccny.cuny.edu few month ago.
Now we just changed the ip address. When I restart ldm process, it is not
getting any data.


Jan 21 20:10:26 halo.sci.ccny.cuny.edu striker[232]: run_requester:
200301211910
26.650 TS_ENDT {{NLDN,  ".*"}}
Jan 21 20:10:26 halo.sci.ccny.cuny.edu striker[232]:
FEEDME(striker.atmos.albany
.edu): 7: Access denied by remote server
Jan 21 20:10:26 halo.sci.ccny.cuny.edu redwood[231]: run_requester:

Jan 21 20:10:27 halo.sci.ccny.cuny.edu redwood[231]:
FEEDME(redwood.atmos.albany
.edu): 7: Access denied by remote server


our host name is halo.sci.ccny.cuny.edu, ip address 134.74.54.89.
Can you verify that our machine can access your server ?

Thank you.

best regards,

Xiaodong Yan,
I see lots of entries like
Jan 21 06:00:03 redwood rpc.ldmd[10824]: gethostbyaddr: failed for
134.74.54.89
Jan 21 06:00:03 redwood rpc.ldmd[10824]: Denying connection from
134.74.54.89

Sometimes several a minute. Looks like there was a reverse DNS lookup
problem.
Then around 23Z, it appears the DNS problem was fixed,
and halo connected.

Jan 21 23:10:35 redwood halo[20974]: Connection from

UNIDATA

It looks like your DNS issue has been resolved. Probably a cached entry
someplace I'd guess. Anycase, it looks like you should be getting data
from redwood now. If not, let me know and I can check further. I'll
assume for now that the problem on striker was resolved at the same
time...
